Piper PA-28-181

Analysis

The airplane veered off the runway surface and collided with terrain. The pilot completed a normal approach and touched down on the runway surface. After a short ground roll the left wing lifted and the airplane began to veer from the runway centerline. The pilot attempted to rectify the heading deviation with use of the aileron and rudder controls. Despite his attempts, the airplane departed the right side of the runway, coming to rest in a ditch. The pilot estimated the winds to be from 160 degrees at 8 knots. An airplane mechanic inspected the wreckage after the accident. He noted no evidence of preimpact mechanical malfunctions or failures with the airplane.
